UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 June 11,2010 Mr. Paul A. Harden Site Vice President FirstEnergy Nuclear Operating Company Beaver Valley Power Station Mail Stop A-BV-SEB1 P.O. Box 4, Route 168 Shippingport, PA 15077

SUBJECT:

BEAVER VALLEY POWER STATION, UNIT NO.2 - REQUEST FOR ADDITIONAL INFORMATION RE: SPENT FUEL POOL RERACK LICENSE AMENDMENT (TAC NO. ME1079)

Dear Mr. Harden:

By letter dated April 9, as supplemented by letters dated June 15, 2009, January 18, March 18, May 3, May 21, and June 1, 2010, FirstEnergy Nuclear Operating Company (the licensee) submitted a license amendment for Beaver Valley Power Station, Unit No.2 (BVPS-2). The proposed amendment would modify Technical Specifications (TSs) to support the installation of high density fuel storage racks in the BVPS-2 spent fuel pool.

The Nuclear Regulatory Commission (NRC) staff is reviewing the submittals and has determined that additional information is needed to complete its review. The specific questions are found in the enclosed request for additional information (RAI). The NRC staff is requesting a response to the RAI within 60 days of receipt.

The NRC staff considers that timely responses to RAls help ensure sufficient time is available for NRC staff review and contribute toward the NRC goal of efficient and effective use of staff resources.

P. Harden

REQUEST FOR ADDITIONAL INFORMATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO THE SPENT FUEL POOL RERACK LICENSE AMENDMENT FIRSTENERGY NUCLEAR OPERATING COMPANY FIRSTENERGY NUCLEAR GENERATION CORP.

OHIO EDISON COMPANY THE TOLEDO EDISON COMPANY BEAVER VALLEY POWER STATION, UNIT NO.2 DOCKET NO. 50-412 By letter dated April 9, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML091210251), as supplemented by letters dated June 15, 2009 (ADAMS Accession No. ML091680614), January 18, 2010 (ADAMS Accession No. ML100191805), March 18, (ADAMS Accession No. NIL100820165), May 3, (ADAMS Accession No. ML101260059), May 21, (ADAMS Accession No. ML101460057), and June 1,2010 (ADAMS Accession No. ML101610118). FirstEnergy Nuclear Operating Company (the licensee) submitted a license amendment for Beaver Valley Power Station, Unit NO.2 (BVPS 2). The proposed amendment would modify Technical Specifications (TSs) to support the installation of high density fuel storage racks in the BVPS-2 spent fuel pool (SFP). In order to complete the review, the Nuclear Regulatory Commission (NRC) staff needs the following additional information:

1. Section 6.6 of the Holtec Report No. HI-2084175, "Licensing Report for Beaver Valley Unit 2 Rerack", which supports the BVPS-2 license amendment request, described a methodology for calculating bulk SFP temperature. This methodology included an allowance for evaporative cooling from the SFP surface. The NRC staff found this to be a non-conservative change in the methodology for determination of the maximum decay heat rate that may be placed in the SFP, compared to that included in the current licensing basis.

Identify the methodology that will be used to control the total decay heat rate of fuel placed in the SFP. Explain how the methodology will maintain current licensing basis margins to pool temperature limits and pool time to boil. Provide appropriate test data and benchmarking to support any assumptions or heat transfer modes included in the methodology that are different from those included in the current licensing basis.
